Influence of Cement Foaming Agent on the Quality of Foamed Concrete

Synthetic blowing agent overview

The synthetic foaming agent used for concrete is a highly concentrated and efficient liquid used to produce lightweight foamed concrete. Foamed concrete is also called foamed lightweight concrete (CLC).

CLC concrete has great potential in the construction of honeycomb lightweight applications, and the use of the correct type of foaming agent will make a huge difference in product properties (such as the mechanical properties of concrete and its resistance, etc.). Synthetic foaming agents are chemical substances that reduce the surface tension of liquids and are widely used in the manufacture of blocks, bricks, CLC concrete, etc. worldwide. Compared with other foaming agents, when high density is required, it can be formed with less energy. It is strongly recommended for use in the construction industry, as the demand for lightweight concrete continues to increase over time.

The influence of cement foaming agent on the quality of foam concrete is very important. A good cement foaming agent can make high-quality foamed concrete. The foam produced by high-quality cement foaming agent has good stability and can be constructed in a low temperature environment. The one-time pouring height is more than twice that of similar cement foaming agents.

The foam produced by the protein foaming agent has good stability, its liquid film is tough, and its mechanical strength is good. It is not easy to crack or excessively deform under the extrusion of the slurry. In addition, it has self-holding water, and the water on the liquid film is not easy to lose under the action of gravity and surface tension. It can maintain the thickness and integrity of the foam liquid film for a long time, so the foam can be retained for a long time without breaking

The foam stability of the blowing agent has three effects on the pores:

(1) The foam of the foaming agent can make most of the foam not disappear, and fix it in the foamed concrete to form pores after the initial setting of the slurry. If the stability of the foam is not good, most or a small part of the foam will burst after pouring, and the formation of pores will be few. Even shortly after pouring, the slurry will collapse. This is usually called a collapsed mold, resulting in pouring. Completely failed

(2) Cement foaming agent foam has good stability, the slurry is not easy to deform during extrusion, and has a certain pressure resistance, making it roughly spherical, and finally a spherical hole with a good hole shape can be formed;

(3) The cement foaming agent has good stability, the foam liquid is not easy to break in the slurry, and it is not easy to form the connected holes formed by the gas confluence after the break. Therefore, it eventually forms an ideal closed hole. The poorer the foam stability, the fewer closed cells and the more connected cells.

Therefore, the stability of the cement foaming agent foam cannot be based on the non-collapse after pouring, but should be based on the three indicators of non-collapse after pouring. The generated pores are approximately spherical and not connected to each other. Most people use the non-collapse after pouring as an index to measure the foam stability of the cement foaming agent. This is actually a misunderstanding of understanding and is the minimum standard for foam stability of cement foaming agents.

When there is no standard test instrument to determine the sinking distance, the stability time can be used to measure the foam stability of the cement foaming agent. The foam stabilization time should meet the initial requirements of the gelling material used. Since the slurry can fix the foam after the initial setting, please keep the shape of the foam and make it pores.

Application of synthetic blowing agent

1. Foaming agent is used to make lightweight (clc) blocks and panels;

2. Blowing agent is used to fill the gap;

Foamed concrete is also very useful for filling voids. Because of its high mobility, it can even be poured into the most inaccessible places. It can be used for planned work, and can quickly provide stability and support in emergency situations;

3. Foaming A gentleman is used for roof insulation;

4. Foaming agent is used to mark CLC blocks, cast-in-place walls, bridge reinforcement wall structures, floor structures, lightweight prefabricated blocks, fire protection, sound insulation, etc.
